Airgun magazine

I use 8mm plastic pneumatic pipe to make a magazine for my airgun. Cut the side of one end of the pipe so you can reach the pellet with your thumbnail. The cut should be about 2 pellets long and abut 1.3 into the pipe , experiment a bit .  then i put the tip in a cup of boiling water for about 30 second to get it softer and then pinch it , holding it while it cools . The makes causes the pipe to hold onto the pellets so they dont just drop out. I then make 4 small cuts so the pipe pinches the waist of the pellet , see pic. The bottom pellet is held in place, holding the rifle upright and when you slide the pellet out it pushes it open slightly so the next pellet moves into its place to be held there.
